' To all whom it may concern.' e i Beit known that I, ARTHUR W. WALKER,

a citizen of the United States, residing at 'I .Malden, inthe countybf Middlesex and specification.

State of Massachusetts, have invented new and\useful Improvements in. Gras-Stoves, (anifoldx of which the following 1s a This invention relatesto gas stoves. More particularly it'relates to improvements in means for introducing the gas and conveying it to the burners. Heretofore it has been customary to run a gas pipe called a man1- fold along the 'outside' of the stove and to install short pipes with cocks, each leading thence to a burnen- It is among the objects of the present invention to provide for the performance ofthe functions of the manifold, but te reduce'the cost of production,

by eliminating elements `and labor that have heretofore been thought necessary; to reduce the space required for a stoveofgiven capacity ;and to make improvements of design possible. "These objects are accomplished by forming a longitudinal chamber inthe cornice of the stove top, runningalong over the burners, orv by otherwise suitably modifying .this arrangement soA that a' chamber is `formed integral with the stove walls,- to

which gas is admitted under its'full pres-l sure in normal and unmixed condltion, and

lfrom which cocks lead to the several burners. Incidentally this provides other advantages, among which may be mentioned some heating of the gas before burning; the saving of friction of gas in pipes andbends, making it possible to get a larger output of heat from a stove of given size when working under a given pressure in the gas mains;

and a stronger attachment for t e cocks, beetal thus' obtained' for holding their screw` threads..

cause of the greater thickness o One embodiment ofthe invention is'illustrated inthe accompanying drawings, but

the invention may be embodied in other forms. It is the purpose of the patent to cover in the appended claim whatever features of patentable novelty exist in the invention disclosed.

' Fig. 2 is a perspective view of another portion of'v a' stove embodying the invention in a dilierent way, being a fragmentary view; a'nd Fig. 43 is a fragmentary view of a detail lembodying the invention in still a different may enter through spaces 14 to mix with the gas while passing through the pipes 12 in the ordinary way. In the embodiment of the invention'represented in Fig., 1 the stove top has a cornice 15 which, unlike the usual cornice, sheltersthe gas supply by the provision of an under wall 16 and a rear wall 17, thus making the chamber 1S which` extends longitudinally along the row of pipes or mixing chambers 12that lead to the burners. The walls of this chamber 18 are integral parts of the top of the stove, the chamber being formed by coring the mold. in which the stove top is cast.y As a result ther is absolutely no joint or possibility of leakage of'ga's from the interior of this Holes are then drilled intothe Vchamber at whatever locations are desired A or convenient for the introduction of a pipe 19 for the inlet of gas and for the introduction of the cocks 13 to lead the gas outward to the burners. This very simple description substantially comprises all that is necessary for an understanding of the invention. It may be observed, however, that the bottom wall 16 may be asily made as thick as desired to engage a number of`threads and so to make a perfectly tight connection of the screw-cocks 13 and of the supply pipe 19. It is also to be noticed that the formation of the walls of this chamber integrally with the stove top facilitates the conduction of heat from the other parts` of the stove top to the walls which confine the gas, so that after the stove has been running a time the'gas will become somewhat heated; also that the straight, large Aand unobstructed ers are in operation that the most remote may get an adequate supply of gas with 11ndiminished pressure.

The apparent elimination of anything in the nature. o f a manifold, which hasbeen a visible characteristic of every gas stove heretofore known to me, 1s made posslble by the construction described, 1s us'eful 1n that it materially simplifies the operation of cleaning the stove and makes possible-a new range of designs of gas stoves. The elimination of this manifold, which ordinarily heretofore hasbeen on the eXtreme outside of the stove, and so has been in danger from suoli shocks and blows incurred intranswho sets up th stove for use it is manifest that the labor kof setting up is considerably reduced,` because no connections need be made to the stove as shipped from the factory except to let the supply pipe 19 into k2li the manifold; and it may be easily arranged by theJ maker so that -this can be Ado'neat either end of the manifold, by providing 'a hole at' each end and a plug 'foithe oneptha't -is not used. The saving of space which re- ."3'0 suits from the reduction. ofthe outside di-A mensions may also be at times amatter 0f considerable importance, especially in housesl of modern construction where kitchens and kitchenettes are'made very small and two 5 or three inches ofadditional space may permit the installation v,of a stove, or of, some other apparatus beside the stove, which could not, otherwise be accommodated.

If this chamber be made of cast metal it canbe made to fitthe shape of the underside of the cornice very muchas if it 'Were integral therewith, but inany event it eliminates the lateral exterior projection that'has characterized gas stoves hitherto, andfit can be tapped for supply and discharge of gases like the -formshoWn in Fig. 1.
